Scientists at the United States National Aeronautics and Space Administration (NASA) have turned their attention from the mysteries of the cosmos to a more esoteric area of research: what happens when you get a spider stoned. Their experiments have shown that common house spiders spin their webs in different ways according to the psychotropic drug they have been given. Nasa scientists believe the research demonstrates that web-spinning spiders can be used to test drugs because the more toxic the chemical, the more deformed was the web.
